Note:This particular Diplexer passes Satellite signal from 950 up to 2050 MHz. The Pass-Band for the Antenna or Cable TV is from 40 to 806 MHz, which is great for HD TV Antenna signals, and Cable TV Systems that have channels up to 750 MHz (Check with your Cable TV System Operator!). Remember that depending on the example scenario you are following from the DISH Network, DirecTV or other DBS Satellite system, you may need more than one, or several of these devices!

Satellite diplexers are used outside to combine and then separate two separate RF Bands: The 950 to 2150 MHz from the Satellite LNB(F) and the Cable TV or Antenna TV channels. The First would combine these two bands for conveyance via a single RG-6 coaxial cable on one side, and then a second satellite diplexer is used on the other to separate the combined signals for connection to separate these Bands for Input to receivers and the like. Some Satellite Receivers will have Diplexer/Separators built in (Confer with your Installation Guide or Spec. Sheet). Satellite diplexers eliminate the need for extra wiring thereby reducing the cost of labor and installation materials necessary to run two separate coaxial cable drops to carry each signal source independantly.

If you have Off-Air Antenna TV Signals mixed with the Satellite Signals, you will need "Wideband" Splitters that have a minmum start frequency of 50 MHz and again, pass up to 2050 or 2150 MHz. (depending on Service). Those Splitters that have a Start Frequency of below 40 MHz are used for carriage of both Satellite and Cable TV with Return Band two way services like H-Speed Internet Broadband Modems and Set Top Pay-per ViewTV Converters.

Conversely, regular Cable TV Antenna Signal Splitters have a start Frequency of 5, 40 or 50 MHz. and a Stop Frequency of 900 or 1000 MHz. (1 GHz.) You could utilize any of those Splitters for distribution use of the Output Signals of the Satellite Receivers to other TV Sets.
